SAW SWAG E.

SIPECIFICATION forming part of Letters Patent No. 380,758, dated April10, 1888.

Application filed January 13, 1888. Serial No. 260,667.

To all whom it may concern.-

Be it known that I, SAMUEL HILL, of Ottawa, in the Province of Ontario,in the Dominion of Canada, have invented certain new and usefulImprovements in Saw-Swages; and I do hereby declare that the followingis a full, clear, and exact description of the same, ref erence beinghad to the accompanying draw ings, in which- Figure l is a sideelevation of my improved saw-swage. Fig. 2 is an end elevation of thesame; and Fig. 3 is a section on line 0000, Fig.1.

My invention has for its object to rapidly swage the teeth of band,circular, and other saws by a swage which can be quickly moved from onetooth to another and swaging effected by a punch struck by a hammer inthe hand of the workman.

My invention consists of a saw-swage having a body slittedlongitudinally to receive the saw, and having a punch at one endand ananvil crosswise at the foot of the punch, and the other end of thebodyprovided witha grooved bar to bear on the teeth and adjustable togive the desired inclination to the swage, whereby the anvil willconform to the pitch of the tooth and the end of the punch shape thepoint when the punch is struck by a hand-hammer.

A is the body of the saw-swage, preferably elbow or are shaped, andprovided with a slit, B, to receive the saw edgewise. At the end of theslit is inserted, in a notch in theiower edge of the body A, ananvil-bar, G, grooved longi tudinally to the form desired to shape thepoint of the tooth.

D is a punch in a socket at that end of the body above the anvil, andagainst the anvil the lower end of the punch impinges when the saw isremoved; but when the saw is inserted in the slit for swaging the toothbears upon the anvil and the punch will rest against the back of thetooth, so that by striking the punch (No me del.)

with a workmans hammer the tooth will be swaged. The lower end of thepunch is shaped to give the desired form to the tooth, and the punch andanvil are removable from the body to allow different-shaped punches andanvils to be interchangeably employed to suit large or small teeth.

E is alongitudinally-grooved bar, to bear on the top of the teeth of thesaw and carry that end of the swage to which it is attached, whereby theswage can be readily moved from one tooth to another by the bar slidingalong the top of the teeth; and said bar E is hungin a slot, J, in theend of the body opposite to the punch by a thumb-screw, F, which. passesthrough one of a series of holes, G,and through an upwardly-projectinglug, E, integral with the bar.

The proper pitch, inclination, or setis given to the swage to suit teethof different sizes and shapes by inserting the thumb screw in a higheror lower hole of the series and through the lug E, when bar E iscorrespondingly raised or lowered by hand, and then by turning the thumbscrew the bar will be clamped in the slot.

H is a handle attached to the body A near the punch end to convenientlyslide the swage from tooth to tooth after the punch has been lifted outof contact with the tooth last swaged.

I claim as my invention- A saw-swage consisting of the body A, providedwith a slit, B, to receive the saw, and having at one end a punch, D,and anvil O at the end of the slit, and the other end of the bodyprovided with holes G and thumb-screw F, and a grooved bar, E, to bearon the top of the saw-teeth, as set forth.

SAMUEL HILL.
